IMPROVEMENT IN HAND-STAMPS.

Specification forming part of Letters Patent No. 19 [,623, dated June 5, 1877; application filed May 21, 1877.

To all whom it may concern Be it known that I, LEONARD TILTON, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Stamp, of which the following is a specification This invention has relation to stamps for printing; and the nature of my invention consists in novel devices for giving positive rotation to the stamp-heads after the impressions are made, in combination with a reciprocating inking-pad, as will be hereinafter explained; also, in means for adjusting the throw of the inking-pad with respect to the printing-faces of the stamp-heads.

In the annexed drawings, Figure 1 is a view of one end of the improved hand-stamp. Fig. 2 is a front View of the stamp, partly in section. Fig. 3 is a View of the end of the stamp opposite to that shown by Fig. 1.

Similar letters of reference indicate corresponding parts.

The letter A designates a rectangular frame adapted to receive and support the stamping devices, and B is the inking-pad, which is so cured to a follower-bar, O, by means of clamps a a, which allow the pad to be removed, and also to be rotated when necessary.

D designates a knob or handle, which is screwed on a stem, D, and fixed rigidly at any desired point thereon by means of a jam nut, b, between which and the frame A is a helical spring, 0, and a rubber cushion, 0 A rubber cushion, 0 is also applied on the stem D, between the follower G and frame A, for preventing noise while using the stamp.

E designates a rotating bar, which is journaled in the ends of the two parallel limbs of frame A, and adapted to carry on two sides the stamp-heads F F, which are secured in their places by clamps e e.

The drawings represent stamp-heads for dating letters, and at the same time canceling the postage-stamps thereon; but a single stamp-head on each side of the bar E'may be used instead of two heads.

On one end of the bar E is keyed a pinion spur-wheel, f, which engages with a larger spur-wheel, g, on a stud, g, fixed to frame A,

and on the outside of wheel g is fixed a fourleaved cam, h, with which a lifting-hook, H, engages, Hook H is pivoted on a stud, i, fixed to one end of the follower-bar O, and kept in contact with the cam h by means of a spring, j.

J designates a stop-wheel, on the periphery of which are shoulders arranged diametrically opposite each other; and K is a lever, which has its fulcrum on a stud, k, and which passes through the'bifurcated end of the followerbar 0. The lower end of lever K is designed to abut against the stops on wheel J when the stamp-heads are in the position shown in the drawings, and hold them in such position.

During the act of making an impression the lever K is free from the stop-wheel, and during the act of raising the machine the weight of the stamp-heads and frame A, assisted by the spring 0, will cause the hook H to give a half-revolution to the bar E, and bring freshlyinked stamp-heads in position for making impressions. The inking of one pair of stampheads is effected at the time of making an impression with the opposite pair of stampheads.

If desired, stamp-heads may be arranged on four sides of a bar, E, and such bar given quarter-turns instead of half-turns, as above described.

I contemplate arranging my stamping devices so that they can be operated by a treadlemotion or by any other convenient power.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In combination with the rotating bar E and the reciprocating inking-pad B, the wheels f g, cam h, lifting-hook H, and the stop-wheel J, and lever K, arranged substantially in the manner and for the purposes described.

2. In combination with the rotating stampheads F and reciprocating inking-pad B, the adjustable knob D, jam-nut b, and spring 0, substantially as described.

LEONARD TILTON.
